Hello, This small series enables the pattern generator for the HDMI block to function correctly without an external HDMI source connected. Without this series there are a few small errors in the timings code which prevents the user from setting the timings, instead they need to be queried from an external device. Patch 1/3 fix the lookup and matching of requested timings to the timings the device supports, this lookup was incorrectly implemented. Patch 2/3 fixes a corner case where the initial timing selected by the driver to have something to report to user-space can't be used correctly if it is the first set of timings the user wish to use. Finally patch 3/3 removes the need for an external HDMI source to operate the pattern generator. Instead of failing when querying DV timings and their is no HDMI signal but the pattern generator is enabled, report the timings programmed by the user. These user programmed timings are then picked up by the pattern generator to produce a test image using those timings. Tested on a few different R-Car Gen3 boards (H3, M3-N) with no regressions. I can finally run all my automated tests without turning on my Xbox! :-) Niklas Söderlund (3): media: i2c: adv748x: Fix lookup of DV timings media: i2c: adv748x: Write initial DV timings to device media: i2c: adv748x: Report correct DV timings for pattern generator drivers/media/i2c/adv748x/adv748x-hdmi.c | 21 +++++++++++++++------ 1 file changed, 15 insertions(+), 6 deletions(-) -- 2.39.2
